The R&S ESR, the world's fastest EMI test receiver, reduces testing times and more reliably detects EMI

10/17/2012

The new R&S ESR test receiver is available in two different models for frequencies ranging from 10 Hz to 3 GHz or 7 GHz to meet the requirements of all users who perform EMC certification on commercial equipment. The R&S EMC32 covers all commercial standards relevant for test houses and EMC labs used by electrical equipment manufacturers and their suppliers.

The R&S ESR from Rohde & Schwarz is yet another example of the company’s technology leadership in the field of EMI test receivers. The test receiver features time domain scan, an FFT-based receiver technology that allows it to perform measurements up to 6000 times faster than other EMI test receivers. Standard-compliant EMC measurements which took hours in the past can now be completed in just seconds, saving users valuable time on the way to obtaining desired results. This measurement method offers great advantages when the DUT can only be operated for short periods for testing, e.g. in the automotive and lighting industry.

The R&S ESR opens up totally new analysis capabilities. The spectrogram function seamlessly displays the analyzed spectrum over time and records measurements for up to five hours, allowing developers to detect sporadic interferers. The frequency mask trigger responds to specific events in a spectrum. If the mask is violated, a trigger is activated. The measurement is stopped, and the user can analyze the exact cause and effect of the interferer. The persistence mode allows users to clearly differentiate between pulse interferers and continuous interference. It displays the probability distribution of occurring frequencies and amplitudes in various colors, making it possible to detect interferers that are hidden by broadband signals.

R&S ESR also offers conventional stepped frequency scan so the user can compare with existing results. The test receiver is also a full-featured spectrum analyzer and offers proven tools such as IF analysis and time domain display, e.g. for click rate analysis.

The R&S ESR not only features outstanding functionality, it also scores top marks for ease of operation and its clearly structured touchscreen. The various measurement modes are distinctly separated, and the operating mode can be switched at the press of a button. Users can easily configure complex measurements and automated test sequences directly on the touchscreen. The R&S EMC32 software can be used to remotely control the R&S ESR and integrate it into complex EMC systems for automated measurement sequences.

The test receiverís application spectrum is as versatile as its diagnostics capabilities. The R&S ESR makes it easy to perform acceptance testing (conducted or radiated) in line with EN/CISPR/FCC on modules, assemblies, household appliances, IT equipment, TVs, radios, etc. In the automotive sector, the R&S ESR is ideal for acceptance testing of vehicles and accessories in line with automobile manufacturer guidelines, also for mobile applications thanks to the DC operation option.
